RADIATOR CAP FOR AUTOMOBILES.

Application filed May 7,

To all whom it may concemr Be it known that we, ADOLPH R. RAMIG, ADAM G.SHAFER, and ALEXANDER J. KRUM- rsox, citizens of the United States, andresidents of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Radiator Caps forAutomobiles, of which the following, reference being had to the drawingaccompanying-and forming a part hereof, is a specification.

This invention relates to a device adapted to be secured to or over theaperture through which water may be poured into the radiator of watercooled internal combustion engines.

Among the objects of the invention is to obtain a cover which is easilyapplied to the aperture of the radiator, which is readily arranged, whenapplied, so that it cannot be removed until means adapted to coact witha locking device are manipulated in a predetermined manner; to obtain acover which is not easily gotten out of order, or manipulated by anunauthorized person, which is readily operated by means of a key, whichis not liable to be broken, which is simple in construction,economically made and durable.

In the drawing referred to Fig. 1 is a top lan view of the radiator capembodying the invention;

Fig. 2 is a vertical longitudinal section of said cap, and

Fig. 3 a vertical section of a screw threaded member of the cap, in apartially completed condition.

And Fig, 4 is an elevation of one end of a punch adapted tosimultaneously complete the construction of the member illustrated inFig. 3 and join it to the member co-acting therewith to form thecompleted device.

A reference character applied to designate a given part indicates saidpart throu bout the several figures of the drawing w erever the sameappears.

A represents a member which is provided with an mverted cup center, a,having the internal annular flange a, and extending arms a", a", one ofsaid arms being provided w1th recess a, 1n wh1ch a lock may be inserted.B represents a rotatable member of a lock, and b a pin which iseccentrically mounted on the end of rotatable 1921. Serial N0. 467,673.

member B. O C, represent recesses in the cylindrical wall of member D,and d an annular groove near the upper end of member D. Member D iscylindrical in form, and of ductile material,as say cast brass,

and at one end thereof is made with the the inclined face (2 of saidring into substantially the same cylindrical lane with the remainder ofthe inner face 0 said member D; said punch being inserted in the holderof a punch press, in the ordinary way. Prior to the forcing the upperend of member D outward, thereby expandin the metal of. said member atsaid upper en said end is inserted in member A, so that when said upperend is expanded, the flange a is contained in the groove d, and cannotbe removed therefrom; but ma be easily turned around in said groove, byturning member around by arms a, a", or otherwise. The lower end ofmember D is provided with screw threads fitting to corresponding screwthreads on the walls of the aperture in the radiator which the device isintended to cover, as threads E. G represents the upper end of theradiator aperture.

To join members A and D so that turning of member A will turn member Dwe provide the bolt F which is longitudinally movable in member A, sothat one end thereof may be forced forward and into oneof the recessesO, G, and to control said longitudinal movement of bolt F, we providethe loop 7 adjacent to one end thereof, in which loop the pin 6 travels,as rotatable member 13 of a lock is turned. The pin 6 travelling in loopf moves said bolt F, 1ongitudinally, and said member B cannot be turneduntil the end of the bolt registers with a recess C, and when said boltis to be moved longitudinally said registration is made, and upon saidbolt F entering one of said recesses C the members A and D are joined,so that rotation of the member A rotates member D and screwthreads E en-20 said arm to gage with the screw threads of -end G of the wall of theradiator aperture, and further turning of said members A, D, turns thedevice on to or off from said end G.

When the bolt F is retracted and withdrawn from the recess 0, after thedevice is mounted on the end G, it cannot be removed therefrom until themember B of the lock is rotated to move bolt F to enter a recess 0,again, while at the same time it can be turned freely, that is, part Athereof can be turned without turning the member D. The device isthereby locked on the end G.

To prevent the device from being turned by the jars incident to drivingan autombile on a road or street, we provide the longitudinally movablepin H, and spring h 1n one of the arms a". I represents a plug in rovidean abutment against which one end of spring h rests, the other endabutting against said plug H.

The end of the spring adjacent to member D is rounded so as toyieldingly engage with the recesses C, C, in said part D; said 85eccentrically mounted on said locking member, in combination with aring-shaped part provided with an annular groove arranged to co-act withsaid flange to 'oin said parts and permit rotation of one t ereofrelative a to the other, a rotatable lock member, and

a longitudinall movable lock member provided with a oop at one endthereof arranged and connected to said rotatable lock member, to co-actwith said eccentrically mounted pin to control the longitudinal:movement of said locking member by the rotation of the locking member onwhich said pin is mounted, said ring-shaped part provided with a recessarranged to register with and receive said longitudinally movable bolt.

2. A radiator cap consistin of a member provided with an invertedcup-shaped member and arms extending radially on opposite sides thereof,said cup-shaped mem ber provided with an inner annular flange, and witha recess adjacent to said cupshaped member adapted to receive arotatably mounted lock cylinder having a pin eccentrically mountedthereon, in combination with an additional member provided with anannular groove arranged to co-act with said annular flange to join saidmembers and permit rotation of one thereof relative to the other, andsaid. additional, member provided with a radially extending recess, anda bolt mounted on said first member and connected, to said eccentricallymounted pin. to be moved lon itudinally thereb into engagement with saidradially exten ing recess to join said members and prevent rotation ofone thereof relative to the other.
